Soundbrenner Core – Much More Than a Vibrating Metronome

Soundbrenner Core Drummer

Soundbrenner are a company that helped to revolutionize metronomes when they introduced their ‘Pulse’ wearable device. They just recently launched a Kickstarter campaign for a vastly upgraded wearable music tool that met its funding goal in minutes.

The Soundbrenner Core is an ingenious little device that aims to tackle some of the most important issues that musicians run in to:

  • Stay in time
  • Stay in tune
  • Monitor loudness (Helps you make better decisions to protect against tinnitus and noise-induced hearing loss)

It does this while also being a functioning smartwatch, which can connect to your phone and show push notifications.

Soundbrenner promises a durable device with a 3-day battery life. This could be a serious tool for any musician.

Vibrating metronome

Feel the beat at a much stronger level of vibration than a regular smartwatch. You can sync the metronome with other band members via Bluetooth MIDI. This promises a much simpler and cost effective setup.

It allows you to set the tempo by tapping the watch. It also includes exercises to play along with daily to improve your rhythm.

If your band members have multiple Soundbrenner Cores then you can connect them together via NFC to sync the tempo. You can also do so using the Soundbrenner Metronome App for your phone.

Decibel Meter

Your hearing is a lot more fragile than you might think.

In my opinion, this is one of the most important elements of this device. The Soundbrenner Core contains the ability to monitor decibel levels and show you when you need to take action to protect your hearing. In these situations, you can either lower the volume or add hearing protection.

Your hearing is your most important asset as a musician. Anything over 80 decibels can be dangerous if listened to for a sustained period.

Hearing damage can actually occur within minutes of the noise exposure at a rock concert (well over 100 Dbs). Listening to your headphones can be actually LOUDER than this! Playing next to a drum set or large amplifier can be even louder again!

A decibel meter can be extremely useful because our ability to recognize loud volumes is very poor, particularly when there are other loud noises around us.

Hearing damage does not just come in the form of limited hearing ability. It also very often causes chronic and life-quality lower tinnitus (a constant ringing in your ears). You will very likely have these problems if you don’t protect your ears as a musician.

The Soundbrenner core also lets you check levels over the length of your session. This could be a great tool to help you recognize and change your habits in future, if required.


The Soundbrenner Core also works as a tuner. The device twists away from its base and can be magnetically connected to a small stickable attachment (included with the device) or any magnetic surface on your instrument.

This negates the need for having a separate tuner. The interface and color scheme looks great to help easily guide your tuning.

Smartwatch capabilities

The Soundbrenner Core also operates with smartwatch capabilities. It shows the date and time, and includes an accelerometer to detect when the screen should be turned on. It can connect to your phone and show push notifications for calls and texts.

The Soundbrenner Core and Soundbrenner Core Steel

This device comes in two different versions. They both contain the same features, therefore the differences are aesthetic. The Soundbrenner Core is the cheaper version, which is made of polycarbonate and aluminum, which includes a silicone watch strap.

The Soundbrenner Core Steel is a slightly more expensive version. It uses steel for the main device and includes a leather watch strap. This also includes an alternative silicone watch strap and a handy pouch.



That’s a lot of music functionality in one device. The Soundbrenner Core promises to bring these together into a device dedicated for musicians. The vibration is built directly as a metronome, the user interface is built specifically for all of the key features described in this article, and the twisting capability is built for it to be used as a metronome.
